And we already saw that in a previous movie. You'll remember that there were two ways that you can write it. We can use the eq matcher or we can use the be == matcher. The second way with the == is less common than the eq matcher, but it is instructive because many of the other comparison operators share this same syntax. So for example, we can expect 100 to be greater than 99. So the matcher is the be > matcher, even though there's a space between it. And in the same way, we can expect 100 to be less than 101. If we have >, <, we also have to have >= and <=. Together these will allow you to compare two values. Just remember that you have to have "be" in front of each of those operators. And that makes sense because it helps it to read as a proper sentence. In addition, we can use the…
